Perhaps one of the greatest quarterbacks in NFL history could be calling it a career.

No, it hasn't come from an anonymous report citing league sources, rather it came from the horses (pun intended) mouth in a candid conversation.

NFL Films' cameras caught Peyton Manning speaking with New England Patriots head coach Bill Belichick at midfield on Sunday after he led his team to a 20-18 victory in the AFC Championship game.

"This might be my last rodeo, Manning told Belichick when they embraced."

Manning also can be heard Belichick that it "sure has been a pleasure."

Manning, 39, will be playing in his fourth NFL title game, with a record of 1-2 that has left his legacy somewhat unfulfilled. A swansong type victory over a hot Carolina Panthers team could go a long way in cementing that legacy as one of the league's best quarterbacks in it's history.

Belichick did not reveal to reporters what he said in response to Manning as NFL Films was unable to pick up what was said.

"Don't have anything to share," Belichick said Monday. "I shared it with Peyton."

Manning remains under contract for 2016 and carries a cap hit of $21.5 million which could handcuff the Broncos who have many unrestricted free agents to take care of this off season.

Manning will become the oldest quarterback in league history to start a Super Bowl game.
